Overview

Develop the interfaces through which people and coding agents discover, adopt and operate blockchain infrastructure. Work spans the developer dashboard, command-line tools, SDKs and management APIs, with responsibility extending through production use. The central challenge is to make complex capabilities usable while preserving clear security boundaries, dependable behavior and enough visibility to understand what customers experience.

Requirements

  • Helpful experience includes API platforms, cloud consoles, SDKs, agent tools, workflow orchestration or metering systems. Blockchain experience is also helpful.

Responsibilities

  • Take projects from problem definition and technical design through implementation, release, measurement and operational support.
  • Design APIs with compatible versioning, useful errors and safe defaults, and build the services and data models behind them.
  • Deliver enterprise capabilities such as roles, single sign-on, key management, audit history and spending controls across the relevant interfaces.
  • Improve developer observability through usage information, request logs and alerts; use adoption data and customer feedback to guide subsequent work.
  • Write design records, runbooks and developer documentation, and review code with product, security, billing and engineering partners.

Conditions
